Latent defect is defined as a hidden structural defect not discoverable by ordinary inspection.

• A. A visible defect discoverable by inspection
• B. A hidden structural defect not discoverable by ordinary inspection
• C. A defect caused by improper maintenance
• D. A cosmetic defect

Answer: (B)

Latent defects are hidden structural problems that ordinary inspection cannot reveal. This means a defect exists but isn’t visible or detectable through a routine check, often requiring deeper investigation or specialized testing to uncover. That’s exactly what the definition describes: a hidden structural flaw not discoverable by ordinary inspection. In contrast, a visible defect can be found during a normal inspection, defects from improper maintenance stem from neglect rather than concealment, and cosmetic defects affect appearance rather than the structure or function. So the option that defines a latent defect as a hidden structural issue not detectable by ordinary inspection best matches the concept.
